To all 11i/0m z' may concern. f

Be it known that l, JULiUs A. PERKINS, a citizen of the United States, and resident of Omaha, in the county of Douglas and State of Nebraska, have invented an Improvement in Dust-Guards, of which the following description, in connection with the accompanying drawing, is a specification, like letters on the drawings representing like Darts.

This invention relating to anti-friction or roller bearings is conlprised in a dust guard which is-not only dust but also Water and oil tight.

This guard comprises a collar on the shaft at the inner end of the journal, said collarhaving 'at its side toward the nearest end of the journal a wide groove and projecting parallel flanges, the inner flange surrounding the inner end of the journal. The complemental part of the tight guard comprises a flange extended from the inner end of the stationary box and overlapping and' nearly touching the outer iange of the collar referred to, and a lianged ring secured to the inner end ofthe box inside the flanged end thereof, said ring entering lthe wide space of the collar, a part of the periphery of the ring 'which has an annular groove nearly' touching the inner side of the outer flange of said collar, the inturned flange at the outer endof said ring nearly touchin the inner side of vthe innermost ange o 'the collar, thereby preventing the escape ofoil from the residuum chamber which is substantially vfilled with oil.

Opposite the annular groove of the ring referred to, the box h'as a complemental groove. These grooves constitute a water'- way, and the end of the box andcollar so constructed serve to prevent dust and water troni entering the box and also prevent oil escaping from the box. The Waterway of the box at a point below the journal has an parts in lon, ,'itudinal section 5 A represents the journal of a. car axle A". The axle near the inner end of the journal is surrounded b v a collar A3 the inner side of which next the box presents a ,space At lStates Patent No. 900199 .1908, the present application being a dile'aving an exterior flange AB. l The box B has on its rear end a flange B', and inside said flange the box has extended from it-'and fast with relation thereto a ring B3 having its outer end flanged, the width of Vthe flanged end of the ring at its outer end being .such as to nearly till the space A* 1n the collar, A3, an inturned iiange of the ringB3 substantially touching the inner side of the interior flange A of said collar thus preventing the escape of oil from the residuum chamber of the box. The residuum or oil chamber `is described in my United flanc-e A5 and an interior vision of the application Ser. No.'169500, filed August 14.-, 1903, on which said patent was granted.4 The vexterior of the ring B3 has an annular groover B4, and the flanged end of the box opposite said groove has an annular groove B5.

When the box and shaft a e in running and this4 application filed March dated October 6,

condition, as in the d awings, the outer ange of the box subsl iti'ally verlaps the I collar and nearly touches the same, and the outer flange of the collar enters the space between the inner side ofthe flange of the box and the exterior of the ring connected with the box, the end of the tlange Ai entering the annular groove B5 and space B4, which below the ournal.

The4 collar and box constructed as described prevent water and dust entering the bearing so as to injure the bearing rollers and journal, and at the same time the oil in constituteI aiwaterway having an outlet Bb the residuum-receptacle C in the bottom of the box is prevented from escapement from the box.

VHaving fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a roller bearing, a collar having twointurned and concentric llanges to present an annular space between them, a box having an annular flange surroundingand appreaching closely the periphery of said collar, and a ring ixcdly mounted on thebox concentric ivith the collar and having .a Hangein a plane at right angles to thc axis of the ring and entering the annular space between between the flanggje of the the tlangei ofv the eollar.v said ring and the surrounding: flange on the box presenting between tht-in a pare into which enters the exterior llange ot' the eollar and substantiallxr f-lose the saine.A

Q. .X bearing eon'ipris-inga box having at itr4 inner end a projecting annular flange and a fixed ring overlapped by said flange, the ring having a flange ln a plane aty right angles to the axis of the journal, a journal within said box, a collar surroundingand rotating: n ith said journal and having two inturned eoneentrie flanges forming between them an annular space aty the side of the eollar facing the box, the collar substantially closing the opening-between the flange of the box and the journal, the flanged end of the ring entering and substantially closing the annular space of the collar but being.,r disengaged from the latter, and the outer flange of the collar entering freely the space box and the outer t-irenlnferenee of the ring.

fl. In a bearing, an axle, a collar thereon presenting?r at the :eide next the end of the journal a flange surrounding a space, a box having atfits inner end a flange nearly tout-.hinglr the) eollar land provided with an outlet and .inside Said flange a flanged rinff. the periphery of the ring being grooved for a naterway, the flange o1" the collar enten ing the space between the ange and ring ot the box whereby water entering' the space bet Ween the flange of the box and the collar may flow Yfrom the outer end ofthe flange weeen of the collar into the waterway and thence escape through the'eutlet in the box.

4. In a bearing, an axle having a journal,

a collar on'said axle near an end ol' said join-nal, presenting at its side nexty thejour nal a flange sarroundingr a space, a box having at its end a flange provided with an outlet and inside said flange a flanged ring, the periphery of the ringand the inner side of the flange of the box being each grooved te constitute a waterway, the flange of the col'- lar entering the Aspace between the .flange and ring of the lbox whereby Water entering thenpaee betwen the flange of the box and the collar may floh" from the flange of the collar into the waterway and thence escape` through the outlet ol the box.l

In a bearing.r an axle having a journal. a eliambered collar on said axle near Said journal, a box having at its bottoni a re siduum -rhaniber to contain oil, and a flanged ring! fixed to and extended from the end of said box and adapted to enterv and move freely in the rhainber of said (collar, the flange of said ring beinzgr inturned toward the axle for a distance to prevent oil in Said residuiun-rhamber from esy'zapingry froni'the end of the boxsustaining said ring.

`n testimonywhereof, I have signed my naine to this epeeifleation. in the presence o two subsrribing witnesses.
